CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 675,211, dated May 28,1901.

Application filed January 25, 1901. Serial No. 44,753. (No model.)

To all whom it may concern:

Be it known that I, FAY HAMMOND, a citizen of the United States,residing at Kahoka, in the county of Clark and State of Missouri, haveinvented certain new-and useful Improvements in Corn-Planters; and I dohere by declare that the followingis a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon. K

The present invention has relation to certain new and usefulimprovements in cornplanters; and the object thereof is to improve theplanter in the several details of construction, whereby the s'ameisrendered easily operative and effective in' its purpose and that willpossess the required strength and dura ility, securing both perfectionin action and simplicity in construction, thereby enhancing the value ofthe machine and rendering the same more acceptable to the farmer.

The invention consists in a corn planter constructed substantially asshown in the drawings and hereinafter described and claimed.

Figure l of the drawings is a side elevation of a corn-planterconstructed in accordance with my invention; Fig. 2, a top plan viewthereof; Fig. 3, a rear end view Fig. 4, a 'detail view in perspectiveof the tri'p-wheel and rod with bearing-plate, which connects with thefeed-hopper slides, the parts being shown in their relative position;Fig. 5, a similar view of the trip-wheel, the axle with clutchboxthereon, the lever with arm, showing it in engagement with the disk onthe clutch-box, and the trip-wheel.

In the accompanying drawings, A represents the frame of thecorn-planter, and a b the transverse braces thereof, which are securedto the sides of the frame in any convenient manner, said frame being ofany suitable form and construction.

The rear of the frame A is provided with the usual drivers seat B andthe scrapers G for the rim of the driving-wheels D, said seat andscrapers being of any suitable form and connected to the frame in anywell-known manner.

The driving-wheels D are mounted upon the axle E in the usual manner, sothat the wheels will revolve thereon similar to the ordinaryvehicle-wheel when not locked to the axle.

Within the driving-wheels D are supplemental wheels F, which are rigidlysecured to the axle E and revolve therewith, the rim of the supplementalwheels being of less width than the width of the driving-wheels and ofless diameter, said supplemental wheels having any desirable number ofspurs 0 upon the rim thereof and which project out beyond the outerperiphery of the driving-wheels. These spurs are adapted to enter theground and make a mark therein to serve as means for guiding thecross-marking, and the supplemental wheels, being of less diameter thanthe diameter of the driving-wheels, are raised from the ground, and asthe rims of the supplemental wheels do not extend beyond the rims of thedriving-wheels a double security is obtained against the supplementalwheels coming against or striking the ground, except the spurs, ashereinbefore described.

The hub d of one of the driving-wheels D has rigidly connected therewithin any suitable manner the section 6 of a clutch-box, the section f ofsaid box being loosely mounted upon the axle E. The two sections of theclutch-box are provided with teeth at their inner ends in the usualmanner, so as to engage with each other when it is desired to lock thetwo sections together, the section f being slidable on the axle E and isformed with an L-shaped locking-slot g, with which engages the pin h,projecting from the axle. The box-section f is rendered spring-actuatedby means of the coiled spring 4; bearing against the outer end thereof,and when the two clutch-box sections are locked together, as shown inFig. 2 of the drawings, the revolution of the driving-wheel, with thebox-section secured to its hub, will cause the axle to revolve with it.

A trip-wheel G is mounted upon the axle E and the coiled springi islocated on the axle between said wheel and the outer end of thebox-section f, so as to render the action of the clutch-box automatic inthrowing the machine into gear.

The trip-wheel G is firmly secured to the center of axle E, said wheelhaving two or more pinsj projecting from the side thereof, which pins innumber should correspond with the number of spurs 0 upon thesupplemental wheels F, and by increasing the number of pins in thetrip-wheel the planter may be converted into a drill. A trip-rod H isprovided, which is operated by the pinsj on the tripwheel G, as shown inFig. 2 of the drawings, said pins striking in succession a bearingplateupon the end of the trip-rod. This trip-rod extends forward to the frontof the frame of the corn-planter and has its bearing therein. A spiralspring 72. has its coils encircling the trip-rod with its endsconnected, respectively, to said rod and to the frame.

The trip-rod His connected to the usual slides Zof suitable hoppers I Jthrough the medium of rods m or by any other suitable and well-knownmeans.

When the axle of the corn-planter is caused to rotate, the pins on thetrip-wheel coming against the bearing-plate on the trip-rod willintermittently operate the slides of the hoppers and discharge thecontents thereof when in the act of planting. Should the clutchbox bereleased from engagement with the axle, the axle would remain stationarywhile the driving-wheels revolved thereon, and thereby the rod wouldcease to operate the slides of the hopper. The coiled spring or upon thefront end of the trip-rod H renders the rod spring-actuated in resumingits normal position after being acted upon by the pins j of thetrip-wheel G. A device is provided for releasing the slidable clutch-boxsection f, in order to throw the machine out of gear when thehopper-slides are not to be operated. The slidable section f of theclutchbox is provided with a disk 0, against which acts an arm 19 whenbrought in contact therewith, said arm being secured to a hand-lever K,pivoted to supports L. When the lever is depressed by the driver uponthe seat of the planter a sufiicient distance to come in contact withthe disk, the slidable section f of the clutch-box will be drawn in,which will disengage the teeth thereof with the teeth of the section e,and thus throw the machine out of gear.

I do not wish to be understood as limiting my invention to anyparticular means of operating the slidable clutch-box section, as anymeans may be substituted for that shown which will be in convenientreach of the driver.

The pivoted hand-lever K has a curved lower end, as shown at q, andconnects with the front of the frame of the machine through the mediumof a suitable chain '1, as shown in Fig. l of the drawings, by whichmeans the front of the frame may be raised, the chain being preferablyconnected to the inner end of the pole M of the machine. A hanger N uponthe supports Lhas connected to itafootlever, arm, or bar 0, to which thechain 1' is also connected, by Which the raising of the front of themachine maybe accomplished by foot-power, or any suitable means maybeused for elevating the front of the frame, as that shown is only one ofmany means that may be successfully employed.

Any suitable foot-lever or device may be used for elevating the front ofthe machine that will successfully attain the object, the foot-lever arm0 being of the usual form employed for this purpose. The arm j) issecured upon the upper end of the lever K, and when said leveris broughtdown in position to cause the arm to engage the disk 0 upon the slidableclutch-box section fin order to slide it away from contact with thesection e, the opposite end of the arm 19 will engage the trip-Wheel Gbetween the spokes thereof, and thereby hold the lever stationary, andalso the slidable clutch-box section out of engagement with the sectione, and at the same time elevate the front of the machine, the engagementof the arm with the disk and the trip-wheel being shown in detail inFig. 5 of the drawlogs.

The front of the frame A has connected thereto a transverse supplementalframe P, from which depend the usual runners or shoes R, suitable bracesconnecting the pole or tongue M with the supplemental frame P, as shownat S, the pole or tongue being connected to the frame of the machine inany preferred manner.

The supplemental frame P may be connected to the main frame A bysuitable hanger-rods s, which engage one of a plurality of holes 25 inthe frame A, so that the supplemental frame may have its height adjustedas required in regulating the depth of planting.

In describing the main and supplemental frames and the several partsconnecting therewith I wish it understood that the same are susceptibleof many changes and modifications, which may be resorted to without inany manner aifecting the'general features of novelty or departing fromthe principle of the invention, any such changes being made as wouldcome within ordinary me chanical judgment.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is
